Wow,  Thanks Breck for what is probably the finest discussion I've seen on 
using  BC-453/R23 IF coils.  At first I was under the impression that those 
IF's  were considered inferior to the Miller parts.  Thanks to you and Breck 
 and Kees and others for correcting that misconception.  





I was holding off making a reply to this topic, but since no one else  has 
make one, here goes:
 
While the ARC-5 85 Kc IF cans are of very high quality, they are not very  
High-Q.  Their coils are air wound, while the Miller coils are on  high-Q 
powdered iron cores.  I believe the Miller coils will give better  
selectivity, if that's what you want.  For AM reception, the ARC-5 coils  may be 
superior.
